Word problem: If 1 yard equals 3 inches, how many inches are in 18 yards?
Mariulka [41]

Answer:

54 inches

Explanation:

From the question, we have that:

1 yard = 3 inches

We are to find the equivalent value of 18 yards in inches. This can be expressed as:

18 yards = x

where x is the unknown value.

Get the value of x by dividing both equations:

\frac{1}{18}=\frac{3}{x}

Cross multiply

\begin{gathered} 1\times x=3\times18 \\  \\ x=54 \end{gathered}

This shows that there are 54 inches in 18 yards
